Performing manual checks before an automated cluster upgrade

Before performing an upgrade or downgrade you must manually check that the cluster is ready, make any required configuration changes, and obtain and install the target ONTAP images.

  1. Reviewing pre-update resources
    Before updating the ONTAP software, you should review resources to understand issues you must resolve, understand new system behavior in the target release, and confirm hardware support.
  2. Reviewing cluster upgrade requirements
    Before updating the ONTAP software, you must verify that your cluster meets the general requirements. Some configurations and features also have requirements that you should understand.
  3. Verifying cluster upgrade limits
    Before upgrading the ONTAP software, you must verify that your cluster does not exceed the platform system limits. SAN also has limits that you should verify in addition to the platform system limits.
  4. Preparing to upgrade nodes using Lenovo Storage Encryption with external key management servers
    If you are using Lenovo Storage Encryption (LSE) and upgrading to ONTAP 9.4 or later, you must use the command line interface (CLI) to delete any server connections before performing the upgrade.
  5. Obtaining ONTAP software images
    To upgrade your cluster to the desired target release of ONTAP, your nodes need access to the ONTAP software image. You must copy the software image from the Lenovo Data Center Support site . For ONTAP 9.4 and later, you can copy the software image directly to a local directory.
